Among those offering free telehealth services are MDLive, Doctors on Demand, Teladoc and EpicMD.

Tropical storm Harvey is still causing problems for those affected… Health systems, obviously, have a plenty of work to aid victims and coming in to help are telehealth providers.

One of them, Florida-based MDLive, will be providing free telehealth consultations to those affected by the storm through September 8th.

San Francisco-based Doctor on Demand is also on board to provide free services. In order to take advantage of their offering, patients have to enter the code "HARVEY2017" into the app or website to redeem a visit with a physician.

Then there's New York-based Teladoc which offers the same service to all affected individuals — not just Teladoc members.

"Our call center reps and board certified and state-licensed physicians are standing by to help those families who have been displaced from their doctors and regular routines, but who still need non-emergency medical care," Teladoc CMO Lewis Levy said in a statement.

Finally, we have Miami's EpicMD offering free medical consultations from U.S. Board Certified primary care physicians and specialists where possible, by phone, video, email or text, to all Houston relief victims through as many registered charitable organizations associated with this effort as possible.

The noble move by these companies comes on the heels of a recent law that changed the face of telemedicine in Texas. Previously, the law required physician-patient relationships to be established with an in-person visit first.
